【3D Printing News】Formnext 2019! A Collection of the Latest Technologies!
The annual Formnext 2019 in Germany has successfully concluded. This international exhibition for new manufacturing technologies always features fierce competition among major 3D printing brands. Speaking of recent breakthroughs in 3D printing technology, the three most common technologies, SLS, SLA, and FDM, have mainly focused on a tug-of-war for precision and complexity. However, this healthy competition has significantly improved the usability of objects. 3DMart's special correspondent is once again going to personally show you: (Further reading: Beginner's Guide: Comparison and Principles of Common 3D Printing Technologies)
Metal 3D printing can be said to be the highlight of this year. Many developers are dedicated to overcoming the shrinkage problems after 3D printing. The items on the table are all metal 3D printed products. The cross-section shows delicate porous structures, making metal printed parts lighter and more material-efficient.
The shiny and smooth T-Rex skull is also made entirely of metal 3D printing. Producing a full-sized metal print of this kind is still not inexpensive.
Why is this 3D printed all-metal electric guitar, displayed in the showcase, so valuable? Because it is a real instrument provided to local rock singers for performances at concerts! This means that its application precision and sound quality have been recognized, making it a very groundbreaking exhibit in on-site metal 3D printing.
Next, the exquisite "wax tree" displayed by the DWS light-curing 3D printer can be said to be a good helper for small-batch manufacturing. The "wax tree" is an important process before investment casting turns into metal. Before metal 3D printing becomes more mature, it is the most common application method for converting 3D printed models into metal.
Since the wax tree directly affects the effect of metal pouring, the 3D printed prototype is crucial. The blue jewelry sample is also one of DWS's 3D printing resins, and the formed structure is very delicate.
In addition to photopolymerization, final applications using the FDM method are also increasing. From furniture to automotive applications, the exhibition showed finished products that can be directly used in large-scale development.
Next up is the post-processed heavy motorcycle model made with SLS. From right to left, they are 3D printing, spray filler, and metallic paint. The visual effects and detail are excellent, and even the ultra-fine suspended pipelines are perfectly intact.
The intricate structural applications for which SLS is known have also led to advancements in software. For SLS 3D printing technology, filling the print volume as much as possible saves cost and time. Previously, engineers would manually optimize the arrangement of objects. Now, new automated software uses computer calculations to automatically determine the most space-saving arrangement. Not only did the on-site exhibition successfully showcase arranged samples, but the speed was also 30 times faster than before!
The SLS 3D printed rhino also showcased different types of structural applications and effects, and emerging technologies also greatly challenge designers' skills, allowing the global industry to grow together.
The design of colored powder 3D printing was also astonishing this time. Since it can produce transparent effects, it performs excellently in prototyping bottled models. The customized 3D printed bottles shown in the picture may appear in the near future. Of course, this is once again thanks to the striking creativity of designers, which even made our special correspondent want to collect them.
Finally, we must visit our Ultimaker booth. The Ultimaker staff are holding recent industrial application cases. Many material manufacturers can also be seen directly using Ultimaker 3D printers for development and testing at the exhibition. As the general agent, 3DMart is also honored.
Metal 3D printing is a key development area in recent years, while other 3D printing technologies are tending towards breaking limitations and creating new opportunities. As the global 3D printing survey data released in 2019 shows, 67% of companies are now recognizing the rise of 3D printing. Now is the time to join the ranks of digital manufacturing!
